FIREPLACE.

Specification of Letters Patent. Patented Aug. 24, 1920.

Application filed April 4, 1917; Serial No. 159,715.

provide a fireplace having a structure that will facilitate the circulation of air around the sides and the rear of the fire-box, whereby cool air may be thoroughly-heated when drawn into the lower passages in the air circulating system of the device, and permitted to follow its natural tendency to rise and then be excluded at points above the fire-box.

A further object of the invention is to provide a plurality of passageways for air, the passageways having inlets and outlets disposed in position for facilitating the intake of cool air for permitting the same to be thoroughly heated before being ejected from the outlet openings of the passageways.

The invention also aims to provide a fireplace that will'eliminate the possibility of the room being filled with the fuel gas ]emitted from the burning fuel in the fireox. Y

A further object ofthe invention is the provision of a single metallic unit constructed to be arranged in the fireplace structure, so that brick and masonry may be built aroundthe fireplace to provide any preferred design while the air passages will not be interfered with.

The above and additional objects are accomplished by such means as are illustrated in the preferred embodiment and in the accompanying drawings, wherein like characters denote like or corresponding parts throughout the several views, in which;

Figure 1 is a vertical transverse section through a' fireplace constructed in accordance with my invention.

Fig. 2is a front elevation of the same. Fig. 3 is a horizontal section on the line 3-3 of Fig. 2.; Fig. 4 is a detail perspective view, partly broken away, illustrating the single metallic unit for providing the air passages.

Referring to the drawing, wherein is illustrated the preferred form of my invention, and in which like numerals of reference indicate corresponding parts through out the several views, A designates the single unit constructed to provide a plurality of an passages for permitting the circulation of air in the desired. manner. The base 1 comprises the walls 2 and 3 which are shaped to conform with the firebox commonly employed in fireplaces. The bottom Wall 3 of the base 1 is slightly larger than the upper wall 2 and is contiguous with the vertical side walls 4, The end edges of the wall 2 are integrally connected with the ad- -jacent vertical walls 5 so, that the walls 4 and 5 at each side of the fire box are disposed in comparatively close relation to provide the side passages 6 and 7. The front of the bottom passage inthe base 1, and the front of the side passages 6 and 7 are closed by thefront wall 8. This wall, however, is provided at each side, adjacent the lower edge thereof with inlet openings9 to permit the air to pass from the atmosphere to the passageways 6 and 7.

A double rear wall is provided and consists of the walls 10 and 11 disposed in close relation at a distance equal to the distance between the walls 4 and 5 thus providing a continuous passageway around the unit. Two passages 12 are provided at the top of the unitand each consists of the walls 13 connected by the short narrow Wall 14, the latterbeing disposed in spaced relation at the top of the unit thus allowing a relatively large opening 15 for forming a smoke and gas exit when the device is mounted in position.

In order that the air passing in through the openings 9 may be deflected downwardly into the base chamber, I have provided a baffle wall 16 at each side of the device, one in each passageway 6 and 7. This Wall projects inwardly from the top of the opening 9 as clearly shown by Fig. 4 of the drawing and then is turned at right angles and extends downwardly terminating at the lower edge of the wall 5. The air, therefore, in entering the passageways must be deflected downwardly to pass through the base chamber and along the walls 16 before posed above the extension 19. The ends of these extensions are connected by end walls- 21 thus forming a vent 22 which extends through the wall B of the building and has communication with the exterior of the building. A suitable cap or cover plate 23 is mounted in the vent for normally closing the same, and it will be obvious that the same may be removed when desired.

This air unit A may be arranged in position against the wall B and below the chimney C after which the masonry may be builtup into place around the sides and front of the unit. The interior of the unit may be lined with fire-brick to form the fire-box D within which the fuel will be burned and the fire-box will have communication with the chimney C through the passageway E, the latter leading through the exit 15. The front of the fireplace structure or masonry will be provided with a plurality of open ings 24 which may be of any desired size for establishing communication between the interior of the room and the interior of the upper passageways 12.

In use, the cool air will pass in through the openings 9, it being natural for the cool air to follow thev lowermost course. The

' air will then circulate in the base chamber,

and be deflected downwardly by the baffie plates 16 after which it will be permitted to circulate around the back and sides through the corresponding passageways, and thus outwardly through the upper passageways seeking an exit through the openings 24. By this time, the air will be thoroughly heated and the continued circulation of air will cause the room to be quickly warmed to the desired temperature while, at the same time, it will permit the entire draft to be maintained on the fire through the chimney 6. The gases, smoke and soot may thereby be carried off through the chimney Without the possibility of gas aceumulating in the room as often happens where it is necessary to partially close the chimney by dampers or the like to direct some of the heat into the room.

Below the fireplace structure is an ash pit 25 having communication with the ash openings 17 and 18. This ash pit is preferably arranged in the basement or cellar, and the ashes from the fireplace may be easily passed through the openings 17 and 18 into the ash pit 25. 1

From the foregoing it will be observed that a very simple and durable fireplace has been provided, the details of which embody the preferred form. I desire it to be understood, however, that slight changes in the minor details of construction may be made without departing from the spirit of the invention or the scope of the claim hereunto appended.

I claim:

A fire place structure comprising a hollow unit provided with double walls at its b0ttom, top, sides and rear, thetop wall being centrally divided to form an opening for the escape of the products of combustion, air exit passages being formed between the double Walls at opposite sides of the opening, the double side walls forming side pas sage ways communicating with said passages, baflie members arranged within said side passage ways, said fire place being provided with a front wall having inlet openings, said bafl'le members being disposed adjacent said inlet openings to direct the incoming air from the inlet openings downwardly to the bottom of the side passages, the rear marginal edge of the bottom wall having a rearwardly extended portion, and the lower marginal edge of the rear wall having an extension above said first mentioned extended portion whereby the two extensions form a vent in communication with the space between said bottom walls.

In testimony whereof I afiix my signature in presence of two witnesses.
